Full licensed assets are a must for a Stranger Things Pin meaning show music, actor audio + video, and custom callouts by one or more of the shows actors. Stern cannot pull a Walking Dead or Guardians with this one. A geneic Stranger Things pin won't work.
Also, I would love to see some D&D elements implemented into the games ruleset that creates a quest like feel for players. A Stranger Things pin needs a LOTR, Hobbit, Star Wars, style ruleset that works the playfield in interesting ways to go through the themes story rather then just hitting ramps and orbits in generic points based modes.
